Asus Essence One Headphone Amp/DAC (CeBIT 2011) - Page 183

post #2731 of 3016

Use the ASIO driver in the drop down menus of Foobar. For the other playback software, either configure bit depth/sampling rate to source or set it at 24/192 if you prefer (not sure everyone can pick up the sonic differences between the bit rates according to source etc).

Hi

I just got muses.

 

Over 9 o clock volume I get humming/hissing.

 

Tried USB and coaxial.

 

I need to keep at 9 o clock and control from my computer to avoid humming/hissing.

 

Used as a dac connected to a tube preamp and then speakers/headphone.

 

Doesn't happen without muses in the chain.

 

By the way, the sound is delicious, outstanding to say the least!

Asus Essence One Muses Edition Impressions

 

SETUP 1

PC – USB – Asus Essence One Muses – Project Ember – AVI ADM 9RS / Sennheiser HD 650

 

SETUP 2

PC – SPDIF – AVI ADM 9RS via Internal DAC

 

SETUP 3

Asus STX – Project Ember – AVI ADM 9RS / Sennheiser HD 650

 

DAC

The Muses Edition is a huge improvement over the other two setups above.

 

Pros over AVI DAC / STX DAC: (Also, AVI DAC >>> STX DAC)

Way more articulate, not even close, a night and day difference

Far more spacious, wider, deeper, taller

Far more natural and lively without being bright

Far more rich, detailed as well as lush

Immerses you in the music and makes you want to dance, unlike the other setups which are more analytical but not as good in the above ways.

Imaging is much better

Dynamics are better

 

Cons over AVI DAC:

Not as transparent or clean

 

PLEASE NOTE

I prefer the Muses to the AVI dac by a huge shot, not even a comparison, especially for the mids and sound stage and because it actually sounds like music with emotion and depth!

 

With HD 650:

It feels as if the music is floating around my head rather than just sitting over there.

Imaging and dynamics are better as I said above.

Melting delicious sound presentation

More balanced yet better all around

Above pros as well

No cons over STX DAC

 

AMP

Not tried much, just for a few seconds. Sounded very good, but not in the same league as the DAC. My Ember sounded slightly better but I haven’t tried the amp much anyway! So can’t really say…

 

Impressions

It doesn’t sound sterile or dead like the other setups. It sounds like music and real, something which immerses you.

 

The AVI DAC is very good, but not in the same league as this DAC (though it is more transparent and cleaner).

This DAC sounds rich and lush while being powerful and articulate.

 

The bass isn’t as prominent as the AVI DAC which isn’t bass heavy either.

 

I never got the WOW effect, not even when I went from Aktimates to AVI ADM, or from Bravo to Ember, and both above are night and day upgrades. But this upgrade gave me the WOW effect that was I missing all along. Now my setup feels complete and truly end game without any upgrade itch in me. Don’t get me wrong, AVI ADM and HD 650 and Project Ember are all excellent at their price points and work exceptionally, but I was probably missing the Source I needed and this Source brings out the best within all my devices/setup and makes them really sing.

 

With Muses, HD 650 sounds like a flagship headphone, not as detailed as the HD 800, but definitely truly end game and the sound presentation is to die for!

Nice impressions :biggrin:

 

Did you overcome the humming problem after 9' O clock? If not make sure all pins are mounted correctly, I've had a similar problem were one of the pins bent underneath itself.

post #2735 of 3016

Which pins are you talking about? Can you please clarify? :(

post #2736 of 3016

Are you talking about the opamps?

post #2737 of 3016

The muses chip has  8 pins on each chip, or did you buy the Muses Edition preloaded with muses chips, if so you take the unit back for a replacement or refund

post #2738 of 3016

Break off the power pin of your USB cable which your asus dac doesn't need or use, because it's self powered unit, which you can find tutorials on head-fi to do this.

 

This may or may not be the problem but at least you will know, and it doesn't effect the performance of the unit itself

post #2739 of 3016

Could you please give a link to the tutorial? Do you think a usb isolator may help?

Practice on a older cable first, If you don't feel confident in doing this than don't

post #2741 of 3016

Before you do that, try optical input. If there is no hiss, then it's a PC side noise issue (some motherboards or PCs can be noisy). If there is still noise, the issue on the E1 side.

post #2742 of 3016

I have tried coaxial, still the same issue :(

Try a different mains power cable, or you could even try a different outlet in your house or somewhere different other then your house

 

I know it's clutching as straws but you never know

Tried a different location, didn't try a different cable though.

 

Also, opened it, none of the pins are bent.

Coaxial is not optical. As I stated earlier try optical (AKA Toslink). There will be no difference between USB and "coaxial" if the noise is coming from the groundplane of the PC side. Toslink (optical) will break the ground connection which is why I suggested you try it.
